UPDATED: In an official statement released by the actor's camp, Christian Bale has denied allegations of assault made by his mother and sister, several hours after he was arrested, questioned by London police and released.

Mr. Bale, who denies the allegation, co-operated throughout, gave his account in full of the events in question and has left the station without any charge being made against him by the police.

"At this time, there will be no further comment by Mr. Bale."
